The-spring then returns the swinging abutment to its inner position.

From the foregoing, it will be seen that.

steam introduced into the hollow shaft will Vpassthrough the passages 2l of the rotor of the member, the passages of which are uncovered by the valve 27.` The steam, passing fromthe passages, willv enter Vthe chambers formed by the swinging abutments 34 and the abutments 14 and thus expand and act' on the abutnients'la to revolve the rotor. As

' soon as an abutment strikes al swinging yabutinent', it'will 'force the swinging abutment rinto its recessV which permits the abutment to pass intoY thernext Vsteam chamber, Ywhich chamberfis immediately placed in communi-V cation'with the exhaustmeans throughthe port land recess :16,s`o that the steam in this chamber will pass toeiihaust. As soon as Vthis abut-mentv passes the' swinging abutment, the swinging :abutment Vwill beY returned byits spring so as to forma space .between itself and the abutment which has v just passed it to receive the steainfroin lthe passageQlV in rear of said abutment. Thus the rotor is propelled by a continuous flow of' steam which i's'exhausted after it has' acted on theabutments of the rotor fora certain period of time, the action being entirely automatic and caused by the revolution ofthe rotor. v

its the par-ts are' so formed in'each mem- 'i ber thatthe rotor can only revolvejin one direction, Ytwo members arevnecessary to pro-` Y Avide an engine whichV can rotate in either Y direction.

Y abutineiitsinone member are koppositely arranged to those 'in the'other member and I4 rlhe swinging abutments vand provide vmeansjffoi moving the swinging Yabutmeiits Bli'of onemember into the ref' 'tcesse's to permitY the rotor of this member to revolve inta reverse direction, this member having its rotor. propelled from theV other ine'mberf 'In this case, the rotor Vofthe member whose swinging abutments" havejb'een moved into'their-recesses, acts as a fly wheel.`

for the engine. y

rThe means for moving the swinging abutia toothed braclet/allonthe device forholding the ring Vin adjusted position. Y The closed endof shaft` 19 ymay be provided L withp'any suitablecoupling,so that this shaft may be connected to the machinery to be driven. Y Y

VWhen the engine is to be driven in one direction, the handle 3l is manipulated to place the valve 27 in proper position to perlmit Vsteam to flow tothe desired member.

tlhis steam will act on the abutments to revolve the rotor as before explained and before the steam is turned on, the handlek 42 is moved to shiftthe ring Y39 on the second member to a position where it will'movethe swinging abutments of said member into the recesses so that the rotor of this member canV revolve in a reverse directionV and `act as a'fly vwheel for the shaft 19. lf the engine is to be rotated in'an opposite direction, the valve 2'? is *shifted to supply steam to the other member and the' ring of the first/mein f bei' is moved .to pocket the swiiigingf.abutf ments thereof while the ring of theA second member is shifted to permit the ysprings to move the swinging abutments out of the pockets. f i l its will be seen, the shaft is directly driven from the rotors andV thepressure is exerted i at right angles to the centerv of the drivev shaft, YAll the wearing parts may be proa vided with detachable faces, Yso Ythat they Ycan be renewed when worn.r
